Seeing Is Not Always Believing
By R. C. Sproul
One comment that Christian pastors sometimes hear from people they are counseling is that it would be easier for them to have a strong faith if they could see God doing the same kinds of miracles today as are recorded in the Bible. The unspoken assumption is that seeing is believing—that the people who lived in Jesus’ day found themselves more readily trusting Him because they could see His great works.
Such comments show the need for a closer reading of Scripture, for there are many cases where seeing great miracles didn’t move observers to faith. For example, John 11 records Jesus’ raising Lazarus from the dead—a convincing sign if there ever was one. Yet the authorities took the miracle as a reason to oppose Jesus, not to believe in Him (vv. 45-53). Scripture also records occasions when even God’s people experienced disbelief after seeing many miracles. Consider Joshua 7, which records what happened at Ai not long after the Israelites conquered Jericho. More Here
